Heigl to star in movie based on ex-FLDS member's book

"Gray's Anatomy" actress Katherine Heigl will star in a feature film adaptation of Carolyn Jessop's best-selling book "Escape," about her life within the Fundamentalist LDS Church.

The Hollywood-industry newspaper Variety reported Tuesday that Heigl will also produce the film. Jessop's book, about her life as the fourth wife of FLDS leader Merrill Jessop and her decision to leave the polygamous sect, has been a huge bestseller.

It is not the only film in development about the FLDS Church. Variety previously reported that "Stolen Innocence" would be made into a movie. That book was written by Elissa Wall, the witness in the case against FLDS leader Warren Jeffs.
